CNN reports that SoftBank is getting ready for a blockbuster IPO.
On Monday, the Japanese company it plans to sell $21 billion worth of stock in its mobile telecoms unit.
That would make it the world's biggest IPO since Alibaba (BABA) went public in New York in 2014.
The IPO is a key part of CEO Masa Son's efforts to reposition SoftBank (SFTBY) as a global tech investor.
SoftBank has also poured money into high-profile tech companies like Uber and its Chinese rival Didi Chuxing.
Selling shares in the mobile division will raise billions of dollars for Son to hunt down more major deals.
